What We Can Learn From
Animals?
each animals has its own uniquecapabilities
some animals have hydrodynamic
form (movement in water)
others use outlandish sensorydevices
Inspired scientist to invent new
devices that can make work/human life
easier

Surface Drag and SwimsuitsInspired by Shark Skin
- These tight fitting suits aremade out of a fabric which wasdesigned to mimic the properties ofa shark's skin by superimposingvertical resin stripes.
- Swimsuits made with new fibers
and weaving techniques are producedto cling tightly to the swimmer'sbody and reduce drag as much aspossible. Research has shown thatsuch garments can reduce drag by 8%over ordinary swimsuits

515-Million-Year-Old Optic Design
- Andrew R. Parker and his colleagues
- how to greatly increase the efficiency ofsolar absorbers and solar panels used to provide
energy for satellites.
- Work is currently under way to reduce the
angular reflection of infrared (heat) and other light
waves by mimicking the fly-eye structure.
- Most suitable for use in solar panel surfaces,the fly-eye grating has also done away with the
necessity for expensive equipment to ensure that these
panels are always directly facing the Sun.

A Solution to Traffic Problems
from Locusts!
Locusts never collide with one another led to theopening of a whole new scientific horizon
Experiments determined that locusts send out an
electronic signal to any body approaching them to
identify that body's location, and then change
direction
This behavior of locusts is being studied that mightbe the solution for heavy traffics

Stenocara: A Fully-Fledged WaterCapturing Unit
- the stenocara's water capture system is
basically a special feature in its back where thesurface is covered in tiny bumps.
- the surface of the regions between each bumpis wax-coated tpyet the bumps themselves are waxfree which lets them collect water productively.
-they extract water vapor from the air which israre because the desert evaporates the droplets
almost immediately due to heat and wind. But dueto its unique design the droplets form on thewings of the stenocara and and the droplets slideto the beetles mouth
- after further examination on the beetlescientist have establishednthabit is a perfectwater trapping model

Birds Flight Methods as a Model for
High-Speed Trains
Bullet Train Has a Nose
Like a Kingfisher Beak The kingfisher dives into the water from
the air without making a splash, mostlythanks to its highly efficiently-shapedbeak.
Eiji Nakatsu realized that the sameshape could solve Japans ultra-fastbullet trains, which created a loudbooming sound like a thunder clap wheneverthey exited a tunnel.
The nose of the train was pushing air athigh speeds, creating a wall of wind thatnot only made the loud sound, but alsoslowed down the train.
The new, kingfisher-inspired train noseeliminates this problem, making the trainsup to 20 percent more fuel efficient.

Owl Flight and High-Speed Train Noise
-owls make the least noise during flight(this is because they're wings have smalltoothed feathers called serrations)
-since owl's have serrations they formsmaller vortexes compared to other birds
thus being minimizing noise during flight
- the Japanese tested on stuffed owlstherefore witnessing the perfect wing designof the said bird
- now they succeeded in reducing the noiseof they're trains using wing shapedpantographs based on the owl's serration

Peacock Feathers and Self-Changing Display Signs
- Keratin protein together with the
brown feather pigment melenin allowlight to refract so we can see thecolors.
- The Japanese were inspired to developreusable display signs, thuseliminating some colors as to display
the desired message ,- -The signs can be used repeatedly andimprint new images
- -With this technology we eliminate theidea of producing new signs as well aswe prevent the use of toxic paints

Bird Skulls Inspire
Lighter, Stronger
Building Materials
Skulls in general are extraordinary
impact-resistant structures and extremely
light at the same time as they protect
the most important organs of an animal
body and this performance and physical
property can be applied in structure or
architecture design, says architect
Andres Harris,
Harris imagines mimicking the materialfor a large pavilion, and the blog
Biomimetic Architecture notes that this
concept could also be applied to cars.

Bio-Inspired Computer
Takes Cues from Cat Brains
The University of Michigan decided to study
the feline brain in order to develop an
intelligent computer.
The idea is that current computers execute
code in a linear fashion, as opposed to the
mammalian brain, which can process many
things at once.
Lu is in the process of developing a
circuit element that behaves like biological
synapses. This memristor can remember past
voltages that passed through it in a way
that is similar to memory and learning in
the brain. Why cats? Computer engineer Wei
Lu says it was simply a more realistic goal
than mimicking the brain of a human.

Bat Sonar Navigation Helps theBlind Get Around
Ultracane wouldnt be possible without study of the waybats get around in pitch blackness.
In the same way that bats can see in the dark using
ultrasonic echoes that reveal the location of obstacles,the Ultracane warns blind users of objects in their path.
A number of sensors on the cane even make it possible forusers to sense objects higher than head height.

Deer Antlers Inspire
Basis of Super-Tough
Materials
Scientists at the University of York in
the UK studied antlers that were cut just
before the stage when stags start dueling,
when they need their antlers to be at
their strongest, and discovered that
during this period, the antlers dry out.
Dry, stiff materials are usually brittle
and easily breakable, but deer antlers
proved to be 2.4 times stronger than wetbone.
engineers: making a material that is both
stiff and tough. The structure of deer
antlers will likely become the basis of
such.

Contact Lenses ofthe Future Inspiredby Gecko Eyes
Scientists have discovered thatgeckos have a series of distinct
concentric zones in their eyes thatmake it possible for them to seecolors at night, an ability fewother creatures have.
These zones have differentrefractive powers, giving geckos amultifocal optical system thatallows light of differentwavelengths to focus on the retinaat the same time.
This makes their eyes 350 timesmore sensitive than humans, andlets them focus on objects atdifferent distances.
The discovery may allow engineersto develop more effective camerasand possibly even multi-focalcontact lenses.

Beer-Foam-Like Bird Feather
Colors Influence Optical
Materials
that shade of blue is
actually produced bynanostructures that self-assemble
in much the same way as beer foam.
color-producing structures in
feathers start out as bubbles of
water inside living cells, and are
replaced with air as the feathergrows. These intricate optical
structures, which look like
sponges with air bubbles under a
microscope, are being used to
create a new generation of optical
materials in the lab.
